Question

Verify by calculating that -a- 5 moles of co2 and 5 moles of water do not have same mass. B- 240g of calcium and 240g of magnesium have a mole ratio of 3:5. 2- tabulate the difference b/w suspension, colloids , solution. 3- how saturated solution is different from unsaturated solution.

Experts plz answer all the questions nicely plz and carefully

Answer 1

a) I mole of co2 = 44 gram bcoz of mole concept
5 moles contain 5 X 44= 220 g
now water
1 mole of water contains 18 g
5 moles contain 5 X 18 =90 g
hence proved
b) 40 g calcium contain 1 mole
240 contain 1/40 X 240 = 6 moles
24 gram of mg contain
I mole
240 g Contains 1/24 X 240 = 10 moles
ratio is 6/10 = 3/5 = 3:5 hence proved
